Answer:

5 dancers

Step-by-step explanation:

We have a total of 15 dancers. From these dancers, 1/3 of them will be wearing hot pink, so we have that:

(1/3) * 15 = 5 dancers

The number of remaining dancers is:

15 - 5 = 10 dancers

These 10 dancers will be divided in half wearing neon green and half wearing neon yellow, so we have that:

10 / 2 = 5 dancers

So the number of dancers wearing neon green is 5 dancers.

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

https://www.coolmath4kids.com/math-help/fractions/adding-and-subtracting-fractions-different-denominators

For example:
1/2 + 1/3

We need to find something called the least common denominator (LCD)... It's really just the LCM of our denominators, 2 and 3.

The LCM of 2 and 3 is 6. So, our LCD 6.

We need to make this our new denominator...

Change the 1/2:

1 x 3 over 2 x 3 = 3/6

Change the 1/3:



1/2 + 1/3 = 3/6 + 2/6

Now we can do it!

(3+2)/6 = 5/6

Which ordered pair is a solution of the equation 2x − y = 9?
gladu [14]

The correct answer is:    [C]:    " (5, 1) ".

__________________

Explanation:

__________________

Choice:  [C]:  " x = 5 " ;  " y = 1 " ;

Note:  Given the equation:  " 2x - y = 9 " .

  → Plug in " 5 " for "x" , and " 1  for " y " ;

to get:   " [2 * 5]  -  [1]   =   10  -  1  =  " 9 " ;  and:  " 9  =  9 " .

So,  Choice:  [C]:  " (5, 1) "  — is the CORRECT ANSWER.

__________________

Let us consider the "other answer choices" ; as follows:

__________________

Choice:  [A]:  "x = - 4 " , "y = 1" ;  Plug in these values for the given equation:

→  " 2x - y = 9 " ;

→  " (2 * -4) - (5) = - 8 - 5 =  " - 13 "  ;  and:  " - 13 ≠ 9 " .

→  So:  Answer choice:  [A]:  is INCORRECT.

__________________

Choice [B]:  "x = -2" , "y = 5" ;  Plug in these values for the given equation:

  "2x - y = 9 " ;

→  " (2 * -2) - (5) = -4 - 5 = -9 ;  and:  " -9 ≠ 9 " .

→  So:  Answer choice:  [B]:  is INCORRECT.

__________________

Choice:  [D]:  "x = 6 " , "y = - 3" ;  Plug in these values for the given equation:

  "2x - y = 9 " ;

→  " (2 * 6) - ( -3) =  12 - (-3)  =  12 + 3  = " 15 " ;  and:  " 15 ≠ 9 " .

→  So:  Answer choice:  [D]:  is INCORRECT.

__________________

     →  The correct answer is:    [C]:    " (5, 1) " .

Emma buys and sells parts.She bought two tires for $35.00 each and later sold them for $65.00 each.She bought rims for $75.00 ea
otez555 [7]

Answer:

Step-by-step explanation:

She bought two tires for $35.00 each. This means that the total amount for which she bought the tires is

35 × 2 = $70

She later sold them for $65.00 each. This means that the total amount for which she sold the tires is

65 × 2 = $130

Her profit from the tires is

130 - 70 = $60

She bought rims for $75.00 each. This means that the total amount for which she bought the rims is

75 × 2 = $150

She later sold them for $136.00 each. This means that the total amount for which she sold the rims is

136 × 2 = $272

Her profit from selling the rims is

272 - 150 = $122

Her total profit is

60 + 122 = $182

Answer:

B: Yes, the participants are grouped by sun exposure, and then both treatments are randomly assigned within each group.

Step-by-step explanation:

Randomized block design is one in which the experimental units are categorized into groups which we call blocks. Thereafter, treatments will be randomly allocated to the experimental units inside each of the blocks.

Now, from the question, we can see that they were grouped in Blocks according to their outdoor activity which is degree of exposure to the sun. Thereafter the individual groups are randomly assigned treatments.

Thus, Option B is correct.
